LAB 138 – Identifying Authorization Bypass Through User-Controlled Key

Course Overview

This lab on Authorization Bypass Through User-Controlled Key assesses the learner’s understanding of how an existing Insecure Direct Object Reference vulnerability in an e-commerce application can be discovered and exploited via parameter tampering.

After completing this lab, the learner will understand how adversaries can exploit such vulnerabilities to bypass authorization and read or modify another user’s data. If the user-controlled key identifies role or session instead of referencing a resource, the adversary may gain privileges or assume another user’s identity.
